If everybody holds bitcoin and do not use it, bitcoin will be useless. So the price will drop to 0. We need to hold some and use most.
i dont think so,bitcoin will always have strong price,and if we hold bitcoin and not use it,it will not make bitcoin useless.
i'm pretty sure that not all people hold their bitcoin,always there some people who spent it,just waiting for the time when so many store accept bitcoin to start use ans spent bitcoin.
